Description

This position will offer you the ability to directly apply your knowledge of protective relaying and controls systems for HV and EHV substations. As a Lead Substation Engineer, you will:

• Lead an engineering and design team, working on a wide range of substation modifications and upgrades to support client requirements and reviews, including creating calculations, document designs, and specifications.
• Prepare relaying philosophies, including selecting relay, control, and communications equipment, developing SCADA and telecommunication concepts and configurations, and overseeing the preparation of I/O assignments and connection diagrams.
• Guide junior and senior‑level engineers and designers in protection and controls engineering design efforts, including providing guidance with the coordination of detailed design phases for all aspects of the engineering work.
• Support assignments that include investigating, troubleshooting, and solving a wide variety of engineering issues.
• Perform analysis and design of single line diagrams, substation relaying & metering diagrams (i.e. A.C. schematic diagrams), and D.C. schematic diagrams.
• Prepare engineering studies for client and peer review.
• Perform independent reviews of work performed by others including calculations and drawing preparation.
• Coordinate and provide guidance to other engineers, project managers, client personnel, and suppliers to ensure a complete and timely design.
• Perform reviews of existing facilities to propose upgrades and replacements, and present findings and recommendations to clients and peers.
• Develop your career via peer‑learning by sharing knowledge with other experienced engineers through Sargent & Lundy’s systems of process and associated “Communities of Practice.”
• Provide guidance as a mentor in the development of less experienced engineers.
• There is the potential for you to travel to client and vendor offices for design reviews and to plant site locations for construction coordination and field verification of designs.

This role offers a hybrid work arrangement, with the expectation of spending three days a week in the office, giving you the flexibility to work remotely for two days.

Dependent upon your location, this opportunity offers a generous relocation package.
